Definition in file sys_mon.h.

Enumeration Type Documentation

SYSM_NOTIFY_TYPE_e

enum SYSM_NOTIFY_TYPE_e

defines entry or exit

Enumerator
SYSM_NOTIFY_ENTER	entry into a task
SYSM_NOTIFY_EXIT	exit from a task

Definition at line 66 of file sys_mon.h.

Function Documentation

SYSM_CheckNotifications()

void SYSM_CheckNotifications

(

void

)

overall system monitoring

checks notifications (state and timestamps) of all system-relevant tasks or functions all checks should be customized corresponding to its timing and state requirements

early exit if nothing to do

Definition at line 152 of file sys_mon.c.

Here is the call graph for this function:

SYSM_ClearAllTimingViolations()

void SYSM_ClearAllTimingViolations

(

void

)

Clears all timing violations (both current and recorded)

This function clears all indicators that a timing violation has happened.

Definition at line 234 of file sys_mon.c.

Here is the call graph for this function:

SYSM_CopyFramStruct()

void SYSM_CopyFramStruct	(	const FRAM_SYS_MON_RECORD_s *const	kpkFrom,
		FRAM_SYS_MON_RECORD_s *	pTo
	)

Copy from the from entry to the to entry.

Parameters

[in]	kpkFrom	pointer to the origin struct
[out]	pTo	pointer to the destination struct

Definition at line 272 of file sys_mon.c.

SYSM_GetRecordedTimingViolations()

void SYSM_GetRecordedTimingViolations

(

SYSM_TIMING_VIOLATION_RESPONSE_s *

pAnswer

)

Returns the timing violation flags determined from fram state.

This function reads the timing states and determines if a violation has occurred.

Parameters

[out]

pAnswer

pointer to a SYSM_TIMING_VIOLATION_RESPONSE_s struct that will be filled by the function

Definition at line 202 of file sys_mon.c.

Here is the call graph for this function:

SYSM_Init()

STD_RETURN_TYPE_e SYSM_Init

(

void

)

initialization function for system monitoring

Has to be called once after startup to initialize and check system monitoring related functionality

Returns

STD_OK if no configuration error detected, otherwise STD_NOT_OK

Definition at line 140 of file sys_mon.c.

Here is the call graph for this function:

SYSM_Notify()

void SYSM_Notify	(	SYSM_TASK_ID_e	taskId,
		SYSM_NOTIFY_TYPE_e	state,
		uint32_t	timestamp
	)

Sets needed bits to indicate that a task is running.

Has to be called in every function using the system monitoring.

Parameters

taskId	task id to notify system monitoring
state	whether function has been called at entry or exit
timestamp	time

Definition at line 185 of file sys_mon.c.

Here is the call graph for this function:

SYSM_UpdateFramData()

void SYSM_UpdateFramData

(

void

)

Commits the stored changes to FRAM if necessary.

Writing to FRAM is costly (in terms of computation time), therefore it is decoupled from the main task of the sys mon module. When called, this function checks the flag sysm_flagFramCopyHasChanges and writes to FRAM if there are changes.
